SURFACE WASTEWATER TREATMENT FROM VARIOUS FRACTIONS OF PETROLEUM PRODUCTS FROM THE TERRITORY OF HIGHWAY INFRASTRUCTURE FACILITIES
Journal Title: Environmental Problems - Year 2019, Vol 4, Issue 2
Abstract
The article is devoted to the parameters of mechanical treatment of surface wastewater generated in the territory of suburban facilities of the highways from petroleum products (PPs) and their separate fractions. It is found that the open settling mode is more promising. The highest effect of treatment from PPs (within the range under study) is achieved at PPs initial concentration of 125 – 210 mg/dm3 on the third day of settling.
